In the simple case where the MobiLink user name maps directly to a valid user ID in your authentication system, the predefined scripts can be used directly in response to the authenticate_user connection event. The authentication code initializes itself based on properties stored in the ml_property table.

If your MobiLink user names are not equivalent to your user IDs, the code must be called indirectly and you must extract or map the user ID from the ml_user value. You do this by writing a Java class.

See Synchronization script writing in Java.

The following is a simple example. In this example, the code in the extractUserID method has been left out because it depends on how the ml_user value maps to a userid. All the work is done in the "authenticate" method of the authentication class.

package com.mycompany.mycode;

import ianywhere.ml.authentication.*;
import ianywhere.ml.script.*;

public class MLEvents
{
    private DBConnectionContext _context;
    private POP3 _pop3;

    public MLEvents( DBConnectionContext context )
    {
        _context = context;
        _pop3 = new POP3( context );
    }

    public void authenticateUser(
      InOutInteger status,
      String userID,
      String password,
      String newPassword )
    {
        String realUserID = extractUserID( userID );
        _pop3.authenticate( status, realUserID, password, newPassword );
    }

    private String extractUserID( String userID )
    {
        // code here to map ml_user to a "real" POP3 user
    }
}

In this example, The POP3 object needs to be initialized with the DBConnectContext object so that it can find its initialization properties. If you do not initialize it this way, you must set the properties in code. For example:

POP3 pop3 = new POP3();
pop3.setServerName( "smtp.sybase.com" );
pop3.setServerPort( 25 );

This applies to any of the authentication classes, although the properties vary by class.
